[Bug 1808657] Re: Ubiquity fails to boot when selecting the Try Kubuntu (live session).

[Darin Miller]

Removing the maybe-ubiquity from the boot params, booted to live session
3 out 3 attempts.

Sometimes the ubiquity boot will fail before the Try/Install menu is
displayed as shown in the attachment.  And it on this hybrid hardware,
Try Kubuntu option always fails (assuming the ubiquity reaches that
point).

Title:
  Ubiquity fails to boot when selecting the Try  Kubuntu (live session).

Status in ubiquity package in Ubuntu:
  New

Bug description:
  When booting to a live usb via UEFI boot on a hybrid Dell Inspiron
  7559 laptop (Intel/Nvidia), the Try "Kubuntu option" hangs.  If maybe-
  ubiquity is removed from the boot parameters, the laptop will live
  boot without issue.  Proceeding directly to install works fine.

  Another workaround is to add "nomodeset" to the boot parameters.  But
  nomodeset forces a VGA boot. VGA on a 4k screen provides a very poor
  Live session experience.

  I will reboot again with quiet mode disabled to see if any  additional
  errors are displayed.
